Wonder what is off the end of the runway? Perhaps he was trying to minimize damage on the ground.
Boise has long runways and there are stll some, not too many, empty fields south of I-84.
Depends on the direction he was going.
Going East there's some warehouse businesses, a Shopko distribution center, outlet mall.
Going West there's a lot of empty land intermixed with residential ranch houses with acreage.
Those are the runway directions. North of airport is town, South is all high mountain desert.
